Abstract

India has such a diverse geographical area that there are floods in some parts and droughts in other parts of the country and same time they co-exist. Large numbers of severe and devastating floods are endangering life and properties. In the state of Odisha, flooding is caused primarily due to Mahanadi River. The flow of water and its level in the river Mahanadi having a catchment area 141000 km2 is controlled by Hirakud dam. The entire deltaic region of Mahanadi River intercepting a catchment of 48700 km2 gets affected by medium to severe flood almost every year causing immense loss to life and property. Study was done to find out reduced level of flood water in different locations of Mahanadi river reach between Hirakud dam and Naraj for 10, 25, 50, and 100 years return period using Hydrologic Engineering Center-River Analysis System (HEC-RAS) model. The study has been accomplished by preparing the basin map for Mahanadi river in HEC-RAS readable format and computing the peak flood for 10 years, 25 years, 50 years, and 100 years return period using Gumbel's distribution. Improvements for the channel cross-section, bank embankment modification, height of flood protection structure such as dikes, levees in the flooded zone were suggested. The peak flood discharge of Mahanadi river at 10 years, 25 years, 50 years, 100 years return have been calculated as 37535.026 m3/s, 45067.19m3/s, 50656.19 m3/s, and 56203.24 m3/s, respectively. Flood flow hydrograph has been prepared for the year 2008 by unsteady flood flow simulation. Around 10 marked location of river stations are prone to flood under 20 year return period. Eight such points were observed to be overtopping the existing banks with a varying height of 1 m to 10 m with reference to existing banks reduced level in subsequent 10 years to 100 years return period in increasing order. The findings of present study suggest the minimum height of dikes, levees to provide protection from flood at different locations of existing banks to be 2 m to 10 m.

Abstract

The present study is done to understand the frequent change in the platform dynamics of river Ganga from Mirzapur to Ballia in Uttar Pradesh. The study is based on sequential river platform maps generated from the time series multispectral datasets, which revealed a periodic pattern of evolution of the river system over the study area. The study depends upon using Landsat sensors that are Trade Marks (TM), Market Stabilization Scheme (MSS), and Enhanced Thematic Mapper (ETM+) acquired through the years 1975 to 2015. The present work deals with Meandering index and Braiding index, which determines the sinuosity, tortuosity, and braiding of the river Ganga to investigate and classify the river into straight, sinuous, and meander category. The study reveals that the sinuosity was increased from 1.38 to 1.56 from 1975 to 2015, whereas the braiding index is observed as 0.6 to 0.26 at one of the Reaches within the study area from 1975 to 2015, which reveals that the river is exhibiting braiding as well as meandering pattern. The study reveals that the platform of river Ganga is shifting continuously, and the factors behind the shifting of river course are natural as well as anthropogenic.

Abstract

The methodology used for assessing the structural integrity of a given material plays as crucial role in predicting the Stress Intensity Factor (SIF) arises between neighbouring cracks. The assessment of laminated composite materials and its crack propagation is well studied and several models are available to numerically draw out close approximation of SIF with that of experimental counterpart. However, drawing such models for dissimilar cracks on composite surface remains a daunting problem owing to higher computational expense required to discover and review the exploratory variable dictating the deformation process. In this research, a detailed study has been done on the SIF determination of semi-elliptical cracks corresponding to different depths and aspect ratios of a composite material through the usage of response surface methodology. The numerical results reported in the study are in close agreement with that of experimental output.

Abstract

The objective of this study is to analyze the effect of tool-work interface temperature observed during turning of AISI 4340 cylindrical steel components in three machining conditions, namely flooded, near-dry, and dry conditions with three separate CNMG-PEF 800 diamond finish Titanium Nitride (TiN) coated carbide cutting tool. The machining parameters considered in this study are cutting velocity, feed rate, and depth of cut. The experiments were planned based on full  factorial design (33) and executed in an All Geared Conventional Lathe. The tool-work interface temperature was observed using a K-type tool-work thermocouple while machining of steel and subsequently, a mathematical model was developed for the tool-work interface temperature values through regression analysis. The significance of the selected machining parameters and their levels on tool-work interface temperature is found by Analysis of Variance (ANOVA) and F-test. The results revealed that machining under near-dry condition exhibited lesser temperature at the tool-work interface, which is the sign of producing better quality products in equivalence with the machining under flooded condition.

Abstract

In lost foam casting process, polystyrene beads are heated to foam and the required pattern is made by polystyrene foam, which is then coated with refractory and placed in a flask backed up with un-bonded sand. The molten metal poured, takes the shape of foam pattern by evaporative action of foam. Whereas in conventional sand casting, a wooden pattern is used to create mold cavity and the cavity is filled with molten metal to get the final shape of casting. In this paper, an experimental analysis was done on lost foam casting process and compared with sand casting processes. The main objective of this study is to investigate and compare the physical parameters like dimensional accuracy, surface finish, and quality of the final product obtained from lost foam casting process and sand casting process. The results from both the processes are observed and compared to find the accurate and precise process among the two processes.

Abstract

The coastal ecosystem environment is exceedingly creative and dynamic monetarily as well as naturally and biologically as geographical and physical procedures, for example, disintegration, statement, flooding and ocean level varieties adjust the beach front land forms persistently. Any little changes in any piece of the coastal ecosystem zone straightforwardly influences the financial improvement and land-utilize administration of each package of landmass. All in all, coastal ecosystem zones are inclined to numerous characteristic perils, for example, beach front disintegration, storm surge, wave, waterfront flooding and typhoon, and so on. It is obvious that the worldwide mean ocean level ascent because of human incited dangerous atmospheric deviations, which has turned into a constant marvel amid the 21st century. It is likewise a principle risk to the seaside biological community. Coastal ecosystem zone in India expect its significance on account of high efficiency of its biological systems, convergence of populace, abuse of characteristic assets, release of waste emanating and city sewage, advancement of different ventures, expanding load on harbours, burst in recreational exercises or more all oil investigation exercises. The decimation and loss of land in waterfront zone because of ocean disintegration is an extreme issue, especially for a state like Odisha, which is confronting an unstable populace and mechanical development as of late. The coastal ecosystem frameworks along the state have been influenced by a few formative exercises, for example, ports, ventures, aquaculture cultivating and other human mediation as beach front barrier on past years and with the present pattern of advancement in the state, it is normal that the consumption of these waterfront biological system may happen in earlier too. Keeping the above verifiable and significance of the seaside biological community, the present examination tries to evaluate the land use and land cover changes during pre and post cyclone Phailin at southern part of Odisha coast.

Abstract

Rainfall-Runoff (R-R) modelling over a river basin is a complex and challenging task for a hydrological scientist. It is almost complicated due to chaos behaviour of R-R data time series. However, since 1972 various techniques are suggested by the world hydrological scientists and shown some extent of success. In this study, a comprehensive review of the models of R-R modelling over river basin from 1972 to 2016 was performed, wherein models of various contribute is studied year-wise. As an outcome, support vector machine and soft-computing, i.e., neural network, fuzzy logic, and genetic algorithm techniques based on statistics have been found to be successfully applied. In numerical modelling, two different architectures of neural network such as BPN and RBF were found more suitable. The BPN was better evaluated over RBF architecture as far as performance and complexity of implementation is concerned. Finally, it is concluded that BPN is sufficient enough to resolve this complex problem since it has shown 80% certainty in prediction of R-R over different river basins. However, obtaining optimum architecture for better performance is mandatory. These evidences are broadly discussed in this review article.
